Abstract

Vector control of an induction motor has permitted fast transient response by decoupling torque and flux. The PI controller has been widely used due to simple control and easy implementation, Matlab model of Induction motor drives is constructed. This paper presents a fuzzy controller of a direct field oriented induction motor drive for high performance. A superiority of the proposed fuzzy controller over conventional PI controller in handling nonlinear induction motor has been effectively demonstrated by comparing speed controller with PI controller under varying operating conditions like step change in speed reference and torque reference. The results validate the robustness and effectiveness of the proposed fuzzy logic controller for high performance of induction motor drive system.
